Application filed July. 11,

To all whom it may concern:

Be it known that I, AUGUST ScHILmNo, a citizen of the United States,residing at the city and county of San Francisco and State ofCalifornia, have invented certain.

new and useful Improvements in Detachable Spouts for Containers, ofwhich the following is a specification.

Certain commodities are packed in vacuum in suitable containers topreserve the strength thereof, and this is particularl Y true in thepacking of cofi'ee. It is wel known that a container of cofi'ee, vacuumpacked, will rapidly deteriorate and lose its strength and aromaafterthe container is opened and the proper closure is notprovided therefor,and it is to overcome these objections particularly in connection withpackages containing cofi'ee, that the present invention is directed.

The present invention has for its principal object to provide a tubularspout provided with a puncturing point adapted for insertion through theend or body of a container, and which, during its insertion, cuts orsevers the material, and provides its own receiving opening, the severedor cut material being curled back or rolled on the main portion toprovide an anchoring flange for the spout. A further object is toprovide aconstruction which permits the easy insertion and removal ofthe spout into and from operative position without cutting a disk toform the insertion opening, which is common in devices of this characternow in use. A further object is to provide a handle or measuring cup,affording a closure for the spout and also afiording a means forinserting the spout and removing the same from operative position.

The invention consists broadly in a tubular member open at one end andfashioned at its opposite end to rovide a puncturing point and a cuttinge ge for assisting in the easy insertion of the point within thematerial. The body is flanged to provide a stop to limit the insertingof the same and is grooved adjacent the flange to provide a recess andshoulder for cooperating with the material acted on by the point in theformation of the opening," whereby the member is rigidly held inposition, there bein further provided a closure forming a hand e, and ameasuring cupmfor the spout.

With the a ve mentioned and other objects in view, the inventionconsists in the 1921. Serial No. 489,748.

novel construction and combination of parts hereinafter described,illustrated in the accompanying drawings and pointed out in the claimshereto appended; it being understood that various changes in the form,protion within the scope of theclaim may be resorted to withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

To more fully comprehend the invention, reference is directed to theaccompanying drawings, wherein- Fig. 1 is a view in elevation of thepreferred embodiment of my invention in inverted position.

Fig. 2 is a view in elevation of the spout with the closure removed.

Fig. 3. is a view in elevation of the spout at the completion of itsinsertion within a receptacle wall.

Fig. 4 is a view similar to Fig. 3 with the spout in locked position.

Fig. 5 is a sectional view taken on line 5-6, Fig. 3.

Fig. 6 is a sectional view taken on line 66, Fig. 4:.

Fig. 7 is aninverted plan view of a container illustrating the openingformed by the insertion of the spout and the manner of curling thematerial providing a reinforcement surrounding the opening.

In the drawings, 1 indicates a tubular body open at its upper end as at2, and at its opposite end is provided with a relatively solidpuncturing point 3, preferably polygonal in cross section with themeeting edges of the respective point faces 4 afiording suitable cuttingedges 5 extending longitudinally of the point to facilitate theinsertion of the point through relatively stiff .material.

The body 1 at the base of thepoint 3 is provided with an annular flange6 affording a top or surface for limiting the insertion of the bodywithin the surface, and immediately below the underside of said flangethe body is provided with an annular groove 7 of a relatively largediameter, providing outwardly curved shoulders 8, one at the base ofeach edge 5, said shoulders affording looking projections 9 at the baseof the point 3' for retaining the member in position in the receptacle.

The faces 4 of the polygonal point 3 is formed with one or moreapertures 10 therein, which provide a communication through portion,size and minor details of constructhe point into the tubular opening 11in the body 1, 'afiording a discharge for the contents of. the receptaclinto which the spout is inserted.

A suitable flexible washer or gasket 12 is adapted to rest on theundersurface of the flange (Sand afiords a sealing means be-' tween theflange and the upper surface of the receptacle, as hereinafterdescribed.

The upper end of the tubular member 1 is adapted to be closed by atubular cup or shell 13 for positioning over the end 14 of the member 1above the flange 6, and said member 13 and end 14 are preferably formedwith one or more flat faces 15, whereby a rotative movement may beimparted to the member 1 to lock the same within the opening in thereceptacle wall formed by the insertion thereof.

The device being constructed as described,

it is inserted into a'receptacle, preferably prising a tube open at one.end and having throughnthe top wall or end thereof, in the followingmanner.

The member 13 is firmly grasped and the apex 16 of the point 3 isspotted in the end wall at a point adjacent its edge. Pressure isapplied to the member 13 which forces the point 3 inwardly, causingedges 5 to cut the material forming the end wall, and the faces 4- onthe continued insertion of the point roll said material inwardly andbackwardly on itself, as at 17 until such time as the surface of thewasher 12 contacts with the outer face of the receptacle wall. A slightrotation is then imparted to the member13, which, in turn, slightlyrotates the member 1 to position the portions 9 of the shoulder 8beneath and in frictional engagement with the cut, curled portions 17 ofthe receptacle wall.

It will be apparent that the material removed by the point 3 in makingits opening is rolled rearwardly, aflording a yieldable retaining flangeor reinforced wall surrounding the opening and to be engaged by theportion 9 of the shoulder 8 to lock the memher 1 in position within itsopening.

It will. be apparent that. on the container strength to support thespout and from which it is desired to pour the contents.

I claim 1 A detachable spout for containers, comits opposite integralend tapered and polygonal in cross section, the sides of the taperedportion disposed at angles to each other with their meeting edgesforming cutting blades, the sides of the tapered portion being providedwith openings communicating with the interior of the tube, an integral.flangeextending annularly of the tube in spaced relation to the base ofsaid tapered portion, the tube intermediate said flange and base of thetapered end being substantially circular in cross section providing alocking projection at the base of the meeting edges of each side of thetapered portion, a flexible washer on the underside of the flange, and aclosure for the tube afl'ording a means for imparting an axial movementthereto when desired. I

lin testimony whereof I have signed my name to this specification. I
